FAQ
Q: Why are lithium batteries cylindrical?
A: Cylindrical cells are small and round, making it possible to stack them in devices of all sizes. Unlike other battery formats, their shape prevents swelling, an undesired phenomenon in batteries where gasses accumulate in the casing.
Q: What is the difference between LiFePO4 prismatic and cylindrical?
A: “lithium battery cylindrical”. Overall, due to the different manufacturing processes, the cylindrical type will have slightly more cycles than the prismatic LiFePO4 cell. Cylindrical cells will be heavier because most of them have steel shells. Prismatic cells are lighter because most of them use stainless steel and aluminum shells.
Q: Are LFP batteries cylindrical?
A: Cylindrical lifepo4 batteries include 18650, 26650, and 32650. These three markets have more batches and the most common ones. There are also some less commonly used cylindrical batteries such as 18500 and 22650. Cylindrical lithium iron phosphate batteries include 18650, 26650, and 32650.
